I haven't put it in their hna4 nvram variable. 

If you mean by hna list the list of routes, then yes, the default route
is set to the old gateway. 

When I go to the "status page" of arbitrary mesh boxes, they list the old
GW as their default route. The command "route -n" also lists the default
route as going via the old GW. When I traceroute from behind such a
node, to google or some other international site, I am going out the old GW.

The old gw no longer advertises a default route via hna4, though DNS and 
NTP is still behind it, via a 10.0.0.1 route, and it even has another 
public route to 196.91.21.0/24, and it has a wan default route set, but
it should not advertise it.

Rebooting the old GW gets the nodes to accept the new GW, which in fact 
DOES advertise 0.0.0.0/0 from it's hna4 nvram variable, so from it's
OLSR messages. 

Then after a while they switch back. I don't get it.

thanks,
Jan
